Hello,
I'm using a password containing commas to mount a remote cifs on my
computer. I recently upgraded the linux kernel on my system to 5.11,
which seems to contain a regression, making the comma a separator even
in the credential file.
I'm using `mount /path/to/mount` to mount the filesystem with the
following contained in `/etc/fstab`:
//domain.tld/share /path/to/mount cifs
noauto,credentials=/home/jkhsjdhjs/.credentials,uid=jkhsjdhjs,gid=jkhsjdhjs,dir_mode=0755,file_mode=0644
0 0
My credential file looks like this:
user=myusername
pass=abc,def
domain=mydomain
With Linux 5.11 or 5.11.1 the following is printed to `dmesg` when
trying to mount the filesystem: `[ 3051.668834] cifs: Unknown parameter
'def'`. This worked fine with 5.10.16 and below, the man page also says
this should work:
Note that a password which contains the delimiter character (i.e. a
comma ',') will fail to be parsed correctly on the command line.
However, the same password defined in the PASSWD environment variable or
via a credentials file (see below) or entered at the password prompt
will be read correctly.
Thus it seems there has been a regression in 5.11. I tried to identifiy
the commit that caused this regression, but wasn't able to. I also
checked if this bug is already known by searching lkml.org and didn't
find anything. Sorry if I missed something.
Best Regards,
Leon Möller
